pip (also known by Python 3's alias pip3) is a package-management system written in Python and is used to install and manage software packages. [4] The Python Software Foundation recommends using pip for installing Python applications and its dependencies during deployment. [5] Pip connects to an online repository of public packages, called the ...
A problem on Linux systems with installing packages from a different distributor is that the resulting long chain of dependencies may lead to a conflicting version of the C standard library (e.g. the GNU C Library), on which thousands of packages depend. If this happens, the user will be prompted to uninstall all of those packages.
The Python Package Index, abbreviated as PyPI (/ ˌ p aɪ p i ˈ aɪ /) and also known as the Cheese Shop (a reference to the Monty Python's Flying Circus sketch "Cheese Shop"), [2]: 8 [3]: 742 is the official third-party software repository for Python. [4] It is analogous to the CPAN repository for Perl [5]: 36 and to the CRAN repository for R.
Synaptic, an example of a package manager. A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs for a computer in a consistent manner.
Summarising the situation in 2013, Richard Stallman identified nine aspects which generally apply to being a GNU package, [1] but he noted that exceptions and flexibility are possible when there are good reasons: [2] The package should say that it is a GNU package. It should be distributed via ftp.gnu.org, or another site offering access to ...
Such input may be in the form of command line switches or an answer file, a file that contains all the necessary parameters. Windows XP and most Linux distributions are examples of operating systems that can be installed with an answer file. In unattended installation, it is assumed that there is no user to help mitigate errors.
Package format is a type of archive containing computer programs and additional metadata needed by package managers; [1] an instance of this type of archive is called a package. While the archive file format itself may be unchanged, package formats carry additional metadata, such as a manifest file or certain directory layouts.
For example, another developer recreated the left-pad package—but released it as version 1.0.0. Since Koçulu published his as version 0.0.3, users continued to encounter problems. [3] Around two hours after the original left-pad package was removed, npm manually "un-un-published" the original 0.0.3 version by restoring a backup. [1]
